Updated 08 July 2005
Using advanced technology in propellants, micro-electronics and new weight-saving materials, the Trident I C4 missile incorporated the multiple independently-targeted vehicle capability of its predecessor Poseidon and provided a range of more than 4,000 nautical miles with a full payload.

Trident C4 Missile fired at a test range
Note the "aerospike" on the nose of the missile.  This is extended when the missile is fired and makes the missile appear aerodynamically longer, thus increasing its stability and range.
